Vacuum Sealing left over Jointing Compound

Hello all

I Hope your are Well.

I have a Couple of Sections of Jointing between the Paving that I need to Replace.

The Jointing Compound is 'Rompox Easy 15kg from Romex' in Basalt.

Doing this is not an Issue, I have done it before and it is very Easy to do.

However, the Smallest Tub that is available is 15Kg which has the Contents Vacuum Sealed as once it is opened it starts to Harden.

I am not going to need anywhere near 15Kg of Jointing Compound to Repair the Sections that need attention.

I will be getting a Vacuum Sealer, so, what I am thinking is that I could Open the Contents of the Jointing Compound and then place a Small amount in multiple Vacuum Sealed Bags, this way if I ever need to Repair a Small Section of Pointing I will not be wasting close to 15Kg of Jointing Compound.

Do you think that this approach would work?

Thanks in advance

Kevin

 

I sometimes use my sous-vide oven for cooking food that I've prepared in a vacuumed sealed bag.
As the bag gets the air sucked-out, some of the juices can get sucked out too which can make a bit of a mess and could block the air pump.
So as soon as I see any juices approaching the top of the bag I stop and seal. It works fine.
Alternatively I vacuum and seal while the food is still frozen.

The only problem I can envisage is that as the air is sucked out of the bag, some of the jointing compound will get sucked out too and may block the air pump.
I'd have thought that zip-lock bags would work almost as well if you squeeze the air out before zipping.

 

Should do if you get the seals to hold ok.

 

Hello

Thanks for the Replies.

When First opened, the Jointing Compound seems Damp so none should get sucked up, I will however keep an eye on that.

I am hoping that if I get a decent Vacuum Sealer, i.e. not a Cheap one at £25 that it should do a Good Job, hopefully.

I sorted a Couple of Small Sections Last Year and it was so annoying that so much Jointing Compound was wasted especially when the 15Kg Tub Costs £45 + PP.

Thanks

From what I read some years ago when I bought my £25 vac sealer - there are 2 types.

The cheaper ones like I have just suck the air out of the bag then seal. Which risk some of the content being sucked out.
The more expensive ones are small cabinets that remove the air from the entire cabinet, so there is no external pressure. You can vac and seal soup in those which is what they use in pricey restaurants.

Best of luck!

 

Likely that the compound is water based acrylic. (Instructions may inform or if water suggested for clean-up}
If this is the case, then placing a water soaked moist rag in the original container will inhibit drying and extend the life of the product. It will however not prevent eventual deteriation or prolong the 'shelf life'.

Hello @infradig

Thanks for the Reply.

I was told by Romex that I could Add Water to the Tub to keep the Surplus Jointing Compound Moist.

I did try this, however, it still did not last too long.

Since it Hardens when exposed to Air, I thought of the Vacuum Sealing Option.

I will try it, probably in the Summer and see how it goes.

Thanks

Kevin

 

@Kevin Cowans I believe you have to keep a layer of water over the surface of it, rather than just some moisture. Might be worth a bit of googling

 

Romex – romex

"Rompox easy" appears to me to be a PU based product which sets vis dampness, the "Rompox D1" appears to be the water emulsifiable one.

As it comes in a vacuum bag I would expose it to as little air and moisture as possible.
